You may have previously seen this picture of the Helix Nebula, which has been called the Eye of God. It is a composite done by the Hubble in 2002. I now use it for my desktop. If you want the larger version for your desktop, click here then click on the image to see the full-size version. This site explains how this kind of formation occurs. I feel the picture is mesmerizingly beautiful.
“I will show wonders in heaven above…” Acts 2:19a

Update 3/24/07: This NASA composite image is one of my most accessed pages through search engines, drawing people from all over the world. I would like to include a NOAO link that explains the image, and the nebula behind it.
